I would recommend everyone jump every 1-3 years in early career just because it's hard to gain upper level skills when people see you as a junior and also you don't yet know what kinds of companies exist to see what you like and don't like. After that, I say stay until you're bored, burnt out, or feeling stagnant.

That said, if you're being promoted and given responsibilities at the pace you would have had you bailed then it's no problem at all really, although I think it puts you at risk of being afraid to leave you job when you emotional should and makes you inflexible in other types of work environments.
